save the violin concerto

I'm not done with homework. Actually, the last bit of it. The one on CME: Responsible Parenting research. I don't understand why people my age need to researching on this very foreign topic.
I know my parents did their own research before, especially my dad. I used to cry 2 hours every night before sleeping. That was roughly 15 years ago, before Jean existed. So he would sit by his bed and read his book, "Why do Babies Cry?" while trying to drown out the noise and hopefully find some remedy to his nightly frustration. But still, gah the research...

Nowadays I find myself doing violin practice in my toilet cus there's a big-enough mirror in there. Just to correct my bowing. I can't draw a completely straight bow, parallel to the bridge all the time. And that's affecting my sound. While I did learn of some formula to get the bow straight, it's hard to apply all the time and in every unique situation. I've been enduring nearly 3 months of intensive technique building and I hope it works. All in a bid to save Mozart's violin concerto. Except for that, all the other dip pieces, including that concerto's cadenza, are in relatively alright shape. Mozart's music is decievingly easy. He's so detailed.. I think he's an ISTJ. Like jy..
